Ben Zobrist was thrown out trying to steal second base against the Mariners and immediately grabbed his left thumb in pain and was taken out of the game.

Zobrist was sliding head first and tried to avoid the tag with his left arm. If you watch closely, the glove hits Zobrist’s hand. The result was that when Zobrist’s hand hits the bag, his thumb was tucked under, smashing into the side of the bag.

If I had to guess, I would say it looks like he dislocated the thumb. When he lifts his hand up, it just doesn’t look like it is in the right place. Also, if it was just a jam, they wouldn’t have been so quick to remove Zobrist from the game with the delay between innings to examine him.

[UPDATE] The team has announced that the thumb was indeed dislocated and was put back in place. He will miss some time but will stay with team on the road trip.
